That’s how to encrypt a document. I have verified the steps I wrote for simply password protecting a document again and they do work.

Yes, the author is correct and these ARE for Word 2007. It isn’t until you actually go to save as that you get the “Tools” option that will appear in the bottom left hand corner of the save dialouge box. Click that and then you seen general options.

friends !
both the author and ‘bad info” are correct.
we can lock our document in both ways.
1). go for save as
2).go to prepare
however in my opinion the method of author is more safe as the user had to enter the correct password two times.
